MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 12 Freescale Semiconductor Electrical Characteristics Figure 2 shows the undershoot and overshoot voltages at the interfaces of the MPC8572E. T/B/G/L/OVDD + 20% T/B/G/L/OVDD + 5% T/B/G/L/OV DD VIH GND GND – 0.3 V VIL GND – 0.7 V Not to Exceed 10% of tCLOCK1 Note: tCLOCK refers to the clock period associated with the respective interface: For I2C and JTAG, tCLOCK references SYSCLK. For DDR, tCLOCK references MCLK. For eTSEC, tCLOCK references EC_GTX_CLK125. For eLBC, tCLOCK references LCLK. Figure 2. Overshoot/Undershoot Voltage for TVDD/BVDD/GVDD/LVDD/OVDD The core voltage must always be provided at nominal 1.1 V. (See Table 2 for actual recommended core voltage). Voltage to the processor interface I/Os are provided through separate sets of supply pins and must be provided at the voltages shown in Table 2. The input voltage threshold scales with respect to the associated I/O supply voltage. TVDD, BVDD, OVDD and LVDD based receivers are simple CMOS I/O circuits and satisfy appropriate LVCMOS type specifications. The DDR2 and DDR3 SDRAM interface uses differential receivers referenced by the externally supplied MVREFn signal (nominally set to GVDD/2) as is appropriate for the SSTL_1.8 electrical signaling standard for DDR2 or 1.5-V electrical signaling for DDR3. The DDR DQS receivers cannot be operated in single-ended fashion. The complement signal must be properly driven and cannot be grounded.

The drive strength of the local bus interface is determined by the configuration of the appropriate bits in PORIMPSCR. 2. The drive strength of the DDR2 or DDR3 interface in half-strength mode is at Tj = 105°C and at GVDD (min). 2.2 Power Sequencing The MPC8572E requires its power rails to be applied in a specific sequence to ensure proper device operation. These requirements are as follows for power up: 1. VDD, AVDD_n, BVDD, LVDD, OVDD, SVDD_SRDS1 and SVDD_SRDS2, TVDD, XVDD_SRDS1 and XVDD_SRDS2 2. GVDD All supplies must be at their stable values within 50 ms. Items on the same line have no ordering requirement with respect to one another. Items on separate lines must be ordered sequentially such that voltage rails on a previous step must reach 90% of their value before the voltage rails on the current step reach 10% of theirs. To guarantee MCKE low during power-on reset, the above sequencing for GVDD is required. If there is no concern about any of the DDR signals being in an indeterminate state during power-on reset, then the sequencing for GVDD is not required. MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 14 Freescale Semiconductor Power Characteristics NOTE From a system standpoint, if any of the I/O power supplies ramp prior to the VDD core supply, the I/Os associated with that I/O supply may drive a logic one or zero during power-on reset, and extra current may be drawn by the device. 3 Power Characteristics The estimated typical power dissipation for the core complex bus (CCB) versus the core frequency for this family of PowerQUICC III devices is shown in Table 4.

Caution: The CCB clock to SYSCLK ratio and e500 core to CCB clock ratio settings must be chosen such that the resulting SYSCLK frequency, e500 (core) frequency, and CCB clock frequency do not exceed their respective maximum or minimum operating frequencies.Refer to Section 19.2, “CCB/SYSCLK PLL Ratio,” and Section 19.3, “e500 Core PLL Ratio,” for ratio settings. 2. Rise and fall times for SYSCLK are measured at 0.6 V and 2.7 V. 3. Timing is guaranteed by design and characterization. 4. This represents the total input jitter—short term and long term—and is guaranteed by design. 5. The SYSCLK driver’s closed loop jitter bandwidth should be <500 kHz at –20 dB. The bandwidth must be set low to allow cascade-connected PLL-based devices to track SYSCLK drivers with the specified jitter. 6. For spread spectrum clocking, guidelines are +0% to –1% down spread at a modulation rate between 20 kHz and 60 kHz on SYSCLK. 4.2 Real Time Clock Timing The RTC input is sampled by the platform clock (CCB clock). The output of the sampling latch is then used as an input to the counters of the PIC and the TimeBase unit of the e500. There is no jitter specification. The minimum pulse width of the RTC signal should be greater than 2x the period of the CCB clock. That is, minimum clock high time is 2 × tCCB, and minimum clock low time is 2 × tCCB. There is no minimum RTC frequency; RTC may be grounded if not needed. 4.3 eTSEC Gigabit Reference Clock Timing Table 6 provides the eTSEC gigabit reference clocks (EC_GTX_CLK125) AC timing specifications for the MPC8572E.

EC_GTX_CLK125 is used to generate the GTX clock for the eTSEC transmitter with 2% degradation.

This represents the total input jitter—short term and long term—and is guaranteed by design. 5. The DDRCLK driver’s closed loop jitter bandwidth should be <500 kHz at –20 dB. The bandwidth must be set low to allow cascade-connected PLL-based devices to track DDRCLK drivers with the specified jitter. 6. For spread spectrum clocking, guidelines are +0% to –1% down spread at a modulation rate between 20 kHz and 60 kHz on DDRCLK. 4.5 Platform to eTSEC FIFO Restrictions Note the following eTSEC FIFO mode maximum speed restrictions based on platform (CCB) frequency.

The DDR controller supports both DDR2 and DDR3 memories. Note that although the minimum data rate for most off-the-shelf DDR3 DIMMs available is 800 MHz, JEDEC specification does allow the DDR3 to run at the data rate as low as 606 MHz. Unless otherwise specified, the AC timing specifications described in this section for DDR3 is applicable for data rate between 606 MHz and 800 MHz, as long as the DC and MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 20 Freescale Semiconductor DDR2 and DDR3 SDRAM Controller AC specifications of the DDR3 memory to be used are compliant to both JEDEC specifications as well as the specifications and requirements described in this MPC8572E hardware specifications document. 6.2.1 DDR2 and DDR3 SDRAM Interface Input AC Timing Specifications Table 14, Table 15, and Table 16 provide the input AC timing specifications for the DDR controller when interfacing to DDR2 and DDR3 SDRAM.

This should be subtracted from the total timing budget. 2. The amount of skew that can be tolerated from MDQS to a corresponding MDQ signal is called tDISKEW.This can be determined by the following equation: tDISKEW =+/–(T/4 – abs(tCISKEW)) where T is the clock period and abs(tCISKEW) is the absolute value of tCISKEW.

Parameter <= 667 MHz Symbol 1 Min Max Unit Notes tDDKHME –0.6 0.6 ns 6 Note: 1. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state) (reference)(state) for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. Output hold time can be read as DDR timing (DD) from the rising or falling edge of the reference clock (KH or KL) until the output went invalid (AX or DX). For example, tDDKHAS symbolizes DDR timing (DD) for the time tMCK memory clock reference (K) goes from the high (H) state until outputs (A) are setup (S) or output valid time. Also, tDDKLDX symbolizes DDR timing (DD) for the time tMCK memory clock reference (K) goes low (L) until data outputs (D) are invalid (X) or data output hold time. 2. All MCK/MCK referenced measurements are made from the crossing of the two signals ±0.1 V. 3. ADDR/CMD includes all DDR SDRAM output signals except MCK/MCK, MCS, and MDQ/MECC/MDM/MDQS. 4. Note that tDDKHMH follows the symbol conventions described in note 1. For example, tDDKHMH describes the DDR timing (DD) from the rising edge of the MCK[n] clock (KH) until the MDQS signal is valid (MH). tDDKHMH can be modified through control of the MDQS override bits (called WR_DATA_DELAY) in the TIMING_CFG_2 register. This typically be set to the same delay as in DDR_SDRAM_CLK_CNTL[CLK_ADJUST]. The timing parameters listed in the table assume that these 2 parameters have been set to the same adjustment value. See the MPC8572E PowerQUICC™ III Integrated Host Processor Family Reference Manual for a description and understanding of the timing modifications enabled by use of these bits. 5. Determined by maximum possible skew between a data strobe (MDQS) and any corresponding bit of data (MDQ), ECC (MECC), or data mask (MDM). The data strobe should be centered inside of the data eye at the pins of the microprocessor. 6. All outputs are referenced to the rising edge of MCK[n] at the pins of the microprocessor. Note that tDDKHMP follows the symbol conventions described in note 1. NOTE For the ADDR/CMD setup and hold specifications in Table 17, it is assumed that the clock control register is set to adjust the memory clocks by 1/2 applied cycle.

However, the FIFO interface provides deliberate skew between the transmitted data and source clock in GMII fashion. When the eTSEC is configured for FIFO modes, all clocks are supplied from external sources to the relevant eTSEC interface. That is, the transmit clock must be applied to the eTSECn’s TSECn_TX_CLK, while the receive clock must be applied to pin TSECn_RX_CLK. The eTSEC internally uses the transmit clock to synchronously generate transmit data and outputs an echoed copy of the transmit clock back on the TSECn_GTX_CLK pin (while transmit data appears on TSECn_TXD[7:0], for example). It is intended that external receivers capture eTSEC transmit data using the clock on TSECn_GTX_CLK as a sourcesynchronous timing reference. Typically, the clock edge that launched the data can be used, because the clock is delayed by the eTSEC to allow acceptable set-up margin at the receiver. Note that there is a relationship between the maximum FIFO speed and the platform (CCB) frequency. For more information see Section 4.5, “Platform to eTSEC FIFO Restrictions.” Table 24 and Table 25 summarize the FIFO AC specifications. Table 24.

For example, the subscript of t RGT represents the TBI (T) receive (RX) clock. Note also that the notation for rise (R) and fall (F) times follows the clock symbol that is being represented. For symbols representing skews, the subscript is skew (SK) followed by the clock that is being skewed (RGT). 2. This implies that PC board design requires clocks to be routed such that an additional trace delay of greater than 1.5 ns will be added to the associated clock signal. 3. For 10 and 100 Mbps, tRGT scales to 400 ns ± 40 ns and 40 ns ± 4 ns, respectively. 4.

Each input of the SerDes receiver differential pair features 50-Ω on-die termination to SGND_SRDS2 (xcorevss). The reference circuit of the SerDes transmitter and receiver is shown in Figure 54. When an eTSEC port is configured to operate in SGMII mode, the parallel interface’s output signals of this eTSEC port can be left floating. The input signals should be terminated based on the guidelines described in Section 21.5, “Connection Recommendations,” as long as such termination does not violate the desired POR configuration requirement on these pins, if applicable. MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 42 Freescale Semiconductor Ethernet: Enhanced Three-Speed Ethernet (eTSEC) When operating in SGMII mode, the eTSEC EC_GTX_CLK125 clock is not required for this port. Instead, SerDes reference clock is required on SD2_REF_CLK and SD2_REF_CLK pins. 8.3.1 DC Requirements for SGMII SD2_REF_CLK and SD2_REF_CLK The characteristics and DC requirements of the separate SerDes reference clock are described in Section 15, “High-Speed Serial Interfaces (HSSI).” 8.3.2 AC Requirements for SGMII SD2_REF_CLK and SD2_REF_CLK Table 36 lists the SGMII SerDes reference clock AC requirements. Note that SD2_REF_CLK and SD2_REF_CLK are not intended to be used with, and should not be clocked by, a spread spectrum clock source. Table 36.

When eTSEC1 is configured to operate in the parallel mode, the TTX_CLK is the maximum clock period of the TSEC1_TX_CLK. When eTSEC1 operates in SGMII mode, the maximum value of tT1588CLK is defined in terms of the recovered clock from SGMII SerDes. For example, for SGMII 10/100/1000 Mbps modes, the maximum value of tT1588CLK is 3600, 360, 72 ns respectively. See the MPC8572E PowerQUICC™ III Integrated Communications Processor Reference Manual for detailed description of TMR_CTRL registers. 2.

The symbols used for timing specifications herein follow the pattern of t(first two letters of functional block)(signal)(state) (reference)(state) for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tMDKHDX symbolizes management data timing (MD) for the time tMDC from clock reference (K) high (H) until data outputs (D) are invalid (X) or data hold time. Also, tMDDVKH symbolizes management data timing (MD) with respect to the time data input signals (D) reach the valid state (V) relative to the tMDC clock reference (K) going to the high (H) state or setup time. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall). 2. This parameter is dependent on the eTSEC system clock speed, which is half of the Platform Frequency (fCCB). The actual ECn_MDC output clock frequency for a specific eTSEC port can be programmed by configuring the MgmtClk bit field of MPC8572E’s MIIMCFG register, based on the platform (CCB) clock running for the device. The formula is: Platform Frequency (CCB)/(2*Frequency Divider determined by MIICFG[MgmtClk] encoding selection). For example, if MIICFG[MgmtClk] = 000 and the platform (CCB) is currently running at 533 MHz, fMDC = 533/(2*4*8) = 533/64 = 8.3 MHz. That is, for a system running at a particular platform frequency (fCCB), the ECn_MDC output clock frequency can be programmed between maximum fMDC = fCCB/64 and minimum fMDC = fCCB/448. Refer to MPC8572E reference manual’s MIIMCFG register section for more detail. 3. The maximum ECn_MDC output clock frequency is defined based on the maximum platform frequency for MPC8572E (600 MHz) divided by 64, while the minimum ECn_MDC output clock frequency is defined based on the minimum platform frequency for MPC8572E (400 MHz) divided by 448, following the formula described in Note 2 above. The typical ECn_MDC output clock frequency of 2.5 MHz is shown for reference purpose per IEEE 802.3 specification. 4. Guaranteed by design. 5. tplb_clk is the platform (CCB) clock.

All outputs are measured from the midpoint voltage of the falling/rising edge of tTCLK to the midpoint of the signal in question. The output timings are measured at the pins. All output timings assume a purely resistive 50-Ω load (see Figure 36). Time-of-flight delays must be added for trace lengths, vias, and connectors in the system. 2. The symbols used for timing specifications herein follow the pattern of t(first two letters of functional block)(signal)(state) (reference)(state) for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tJTDVKH symbolizes JTAG device timing (JT) with respect to the time data input signals (D) reaching the valid state (V) relative to the tJTG clock reference (K) going to the high (H) state or setup time. Also, tJTDXKH symbolizes JTAG timing (JT) with respect to the time data input signals (D) went invalid (X) relative to the tJTG clock reference (K) going to the high (H) state. Note that, in general, the clock reference symbol representation is based on three letters representing the clock of a particular functional. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall). 3. TRST is an asynchronous level sensitive signal.

For example, tI2DVKH symbolizes I 2C timing (I2) with respect to the time data input signals (D) reach the valid state (V) relative to the tI2C clock reference (K) going to the high (H) state or setup time. Also, tI2SXKL symbolizes I2C timing (I2) for the time that the data with respect to the START condition (S) went invalid (X) relative to the tI2C clock reference (K) going to the low (L) state or hold time. Also, tI2PVKH symbolizes I2C timing (I2) for the time that the data with respect to the STOP condition (P) reaching the valid state (V) relative to the tI2C clock reference (K) going to the high (H) state or setup time. 2. As a transmitter, the MPC8572E provides a delay time of at least 300 ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the undefined region of the falling edge of SCL to avoid unintended generation of START or STOP condition. When the MPC8572E acts as the I2C bus master while transmitting, the MPC8572E drives both SCL and SDA. As long as the load on SCL and SDA are balanced, the MPC8572E would not cause unintended generation of START or STOP condition. Therefore, the 300 ns SDA output delay time is not a concern. If, under some rare condition, the 300 ns SDA output delay time is required for the MPC8572E as transmitter, applicat ion note AN2919 referred to in note 4 below is recommended. 3.The maximum tI2OVKL has only to be met if the device does not stretch the LOW period (tI2CL) of the SCL signal. 4. The requirements for I2C frequency calculation must be followed. Refer to Freescale application note AN2919, Determining the I2C Frequency Divider Ratio for SCL.

GPIO AC Test Load 15 High-Speed Serial Interfaces (HSSI) The MPC8572E features two Serializer/Deserializer (SerDes) interfaces to be used for high-speed serial interconnect applications. The SerDes1 interface can be used for PCI Express and/or Serial RapidIO data transfers. The SerDes2 is dedicated for SGMII application. This section describes the common portion of SerDes DC electrical specifications, which is the DC requirement for SerDes Reference Clocks. The SerDes data lane’s transmitter and receiver reference circuits are also shown. 15.1 Signal Terms Definition The SerDes utilizes differential signaling to transfer data across the serial link. This section defines terms used in the description and specification of differential signals. Figure 43 shows how the signals are defined. For illustration purpose, only one SerDes lane is used for description. The figure shows waveform for either a transmitter output (SDn_TX and SDn_TX) or a receiver input (SDn_RX and SDn_RX). Each signal swings between A Volts and B Volts where A > B. Using this waveform, the definitions are as follows. To simplify illustration, the following definitions assume that the SerDes transmitter and receiver operate in a fully symmetrical differential signaling environment. 1. Single-Ended Swing The transmitter output signals and the receiver input signals SDn_TX, SDn_TX, SDn_RX and SDn_RX each have a peak-to-peak swing of A - B Volts. This is also referred as each signal wire’s Single-Ended Swing.

Differential Output Voltage, VOD (or Differential Output Swing): The Differential Output Voltage (or Swing) of the transmitter, VOD, is defined as the difference of the two complimentary output voltages: VSDn_TX – VSDn_TX. The VOD value can be either positive or negative. 3. Differential Input Voltage, VID (or Differential Input Swing): The Differential Input Voltage (or Swing) of the receiver, VID, is defined as the difference of the two complimentary input voltages: VSDn_RX - VSDn_RX. The VID value can be either positive or negative. 4. Differential Peak Voltage, VDIFFp The peak value of the differential transmitter output signal or the differential receiver input signal is defined as Differential Peak Voltage, VDIFFp = |A – B| Volts. 5. Differential Peak-to-Peak, VDIFFp-p Because the differential output signal of the transmitter and the differential input signal of the receiver each range from A – B to –(A – B) Volts, the peak-to-peak value of the differential transmitter output signal or the differential receiver input signal is defined as Differential Peak-to-Peak Voltage, VDIFFp-p = 2*VDIFFp = 2 * |(A – B)| Volts, which is twice of differential swing in amplitude, or twice of the differential peak. For example, the output differential peak-peak voltage can also be calculated as VTX-DIFFp-p = 2*|VOD|. 6. Differential Waveform 1. The differential waveform is constructed by subtracting the inverting signal (SDn_TX, for example) from the non-inverting signal (SDn_TX, for example) within a differential pair. There is only one signal trace curve in a differential waveform. The voltage represented in the differential waveform is not referenced to ground. Refer to Figure 52 as an example for differential waveform. 2. Common Mode Voltage, Vcm The Common Mode Voltage is equal to one half of the sum of the voltages between each conductor of a balanced interchange circuit and ground. In this example, for SerDes output, V cm_out = (VSDn_TX + VSDn_TX)/2 = (A + B) / 2, which is the arithmetic mean of the two complimentary output voltages within a differential pair. In a system, the common mode voltage may often differ from one component’s output to the other’s input. Sometimes, it may be even different between the receiver input and driver output circuits within the same component. It is also referred as the DC offset in some occasion. MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 72 Freescale Semiconductor High-Speed Serial Interfaces (HSSI) SDn_TX or SDn_RX A Volts Vcm = (A + B) / 2 SDn_TX or SDn_RX B Volts Differential Swing, VID or VOD = A – B Differential Peak Voltage, VDIFFp = |A – B| Differential Peak-Peak Voltage, VDIFFpp = 2*VDIFFp (not shown) Figure 43. Differential Voltage Definitions for Transmitter or Receiver To illustrate these definitions using real values, consider the case of a CML (Current Mode Logic) transmitter that has a common mode voltage of 2.25 V and each of its outputs, TD and TD, has a swing that goes between 2.5 V and 2.0 V. Using these values, the peak-to-peak voltage swing of each signal (TD or TD) is 500 mV p-p, which is referred as the single-ended swing for each signal. In this example, because the differential signaling environment is fully symmetrical, the transmitter output’s differential swing (VOD) has the same amplitude as each signal’s single-ended swing. The differential output signal ranges between 500 mV and –500 mV, in other words, VOD is 500 mV in one phase and –500 mV in the other phase. The peak differential voltage (VDIFFp) is 500 mV. The peak-to-peak differential voltage (VDIFFp-p) is 1000 mV p-p. 15.2 SerDes Reference Clocks The SerDes reference clock inputs are applied to an internal PLL whose output creates the clock used by the corresponding SerDes lanes. The SerDes reference clocks inputs are SD1_REF_CLK and SD1_REF_CLK for PCI Express and Serial RapidIO, or SD2_REF_CLK and SD2_REF_CLK for the SGMII interface respectively. The following sections describe the SerDes reference clock requirements and some application information. 15.2.1 SerDes Reference Clock Receiver Characteristics Figure 44 shows a receiver reference diagram of the SerDes reference clocks. Characteristics are as follows: • The supply voltage requirements for XVDD_SRDS2 are specified in Table 1 and Table 2. • SerDes Reference Clock Receiver Reference Circuit Structure — The SDn_REF_CLK and SDn_REF_CLK are internally AC-coupled differential inputs as shown in Figure 44. Each differential clock input (SDn_REF_CLK or SDn_REF_CLK) has on-chip 50-Ω termination to SGND_SRDSn (xcorevss) followed by on-chip AC-coupling. MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 Freescale Semiconductor 73 High-Speed Serial Interfaces (HSSI) • • — The external reference clock driver must be able to drive this termination. — The SerDes reference clock input can be either differential or single-ended. Refer to the Differential Mode and Single-ended Mode description below for further detailed requirements. The maximum average current requirement that also determines the common mode voltage range — When the SerDes reference clock differential inputs are DC coupled externally with the clock driver chip, the maximum average current allowed for each input pin is 8 mA. In this case, the exact common mode input voltage is not critical as long as it is within the range allowed by the maximum average current of 8 mA (refer to the following bullet for more detail), because the input is AC-coupled on-chip. — This current limitation sets the maximum common mode input voltage to be less than 0.4 V (0.4 V/50 = 8 mA) while the minimum common mode input level is 0.1 V above SGND_SRDSn (xcorevss). For example, a clock with a 50/50 duty cycle can be produced by a clock driver with output driven by its current source from 0 mA to 16 mA (0-0.8 V), such that each phase of the differential input has a single-ended swing from 0 V to 800 mV with the common mode voltage at 400 mV. — If the device driving the SDn_REF_CLK and SDn_REF_CLK inputs cannot drive 50 Ω to SGND_SRDSn (xcorevss) DC, or it exceeds the maximum input current limitations, then it must be AC-coupled off-chip. The input amplitude requirement — This requirement is described in detail in the following sections. 50 Ω SDn_REF_CLK Input Amp SDn_REF_CLK 50 Ω Figure 44. Receiver of SerDes Reference Clocks 15.2.2 DC Level Requirement for SerDes Reference Clocks The DC level requirement for the MPC8572E SerDes reference clock inputs is different depending on the signaling mode used to connect the clock driver chip and SerDes reference clock inputs as described below. • Differential Mode — The input amplitude of the differential clock must be between 400mV and 1600mV differential peak-peak (or between 200mV and 800mV differential peak). In other words, each signal wire MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 74 Freescale Semiconductor High-Speed Serial Interfaces (HSSI) • of the differential pair must have a single-ended swing less than 800mV and greater than 200mV. This requirement is the same for both external DC-coupled or AC-coupled connection. — For external DC-coupled connection, as described in Section 15.2.1, “SerDes Reference Clock Receiver Characteristics,” the maximum average current requirements sets the requirement for average voltage (common mode voltage) to be between 100 mV and 400 mV. Figure 45 shows the SerDes reference clock input requirement for DC-coupled connection scheme. — For external AC-coupled connection, there is no common mode voltage requirement for the clock driver. Because the external AC-coupling capacitor blocks the DC level, the clock driver and the SerDes reference clock receiver operate in different command mode voltages. The SerDes reference clock receiver in this connection scheme has its common mode voltage set to SGND_SRDSn. Each signal wire of the differential inputs is allowed to swing below and above the command mode voltage (SGND_SRDSn). Figure 46 shows the SerDes reference clock input requirement for AC-coupled connection scheme. Single-ended Mode — The reference clock can also be single-ended. The SDn_REF_CLK input amplitude (single-ended swing) must be between 400 mV and 800 mV peak-peak (from Vmin to Vmax) with SDn_REF_CLK either left unconnected or tied to ground. — The SDn_REF_CLK input average voltage must be between 200 and 400 mV. Figure 47 shows the SerDes reference clock input requirement for single-ended signaling mode. — To meet the input amplitude requirement, the reference clock inputs might need to be DC or AC-coupled externally. For the best noise performance, the reference of the clock could be DC or AC-coupled into the unused phase (SDn_REF_CLK) through the same source impedance as the clock input (SDn_REF_CLK) in use. SDn_REF_CLK 200mV < Input Amplitude or Differential Peak < 800 mV Vmax 100 mV < Vcm SDn_REF_CLK < 800 mV < 400 mV Vmin >0V Figure 45.

Single-Ended Reference Clock Input DC Requirements 15.2.3 • • • Interfacing With Other Differential Signaling Levels With on-chip termination to SGND_SRDSn (xcorevss), the differential reference clocks inputs are HCSL (High-Speed Current Steering Logic) compatible DC-coupled. Many other low voltage differential type outputs like LVDS (Low Voltage Differential Signaling) can be used but may need to be AC-coupled due to the limited common mode input range allowed (100 to 400 mV) for DC-coupled connection. LVPECL outputs can produce signal with too large amplitude and may need to be DC-biased at clock driver output first, then followed with series attenuation resistor to reduce the amplitude, additionally to AC-coupling. MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 76 Freescale Semiconductor High-Speed Serial Interfaces (HSSI) NOTE Figure 48 to Figure 51 below are for conceptual reference only. Due to the fact that clock driver chip's internal structure, output impedance and termination requirements are different between various clock driver chip manufacturers, it is very possible that the clock circuit reference designs provided by clock driver chip vendor are different from what is shown below. They might also vary from one vendor to the other. Therefore, Freescale Semiconductor can neither provide the optimal clock driver reference circuits, nor guarantee the correctness of the following clock driver connection reference circuits. The system designer is recommended to contact the selected clock driver chip vendor for the optimal reference circuits with the MPC8572E SerDes reference clock receiver requirement provided in this document. Figure 48 shows the SerDes reference clock connection reference circuits for HCSL type clock driver. It assumes that the DC levels of the clock driver chip is compatible with MPC8572E SerDes reference clock input’s DC requirement.

Because LVDS clock driver’s common mode voltage is higher than the MPC8572E SerDes reference clock input’s allowed range (100 to 400mV), AC-coupled connection scheme must be used. It assumes the LVDS output driver features 50-Ω termination resistor. It also assumes that the LVDS transmitter establishes its own common mode level without relying on the receiver or other external component.

AC-Coupled Differential Connection with LVDS Clock Driver (Reference Only) Figure 50 shows the SerDes reference clock connection reference circuits for LVPECL type clock driver. Because LVPECL driver’s DC levels (both common mode voltages and output swing) are incompatible with MPC8572E SerDes reference clock input’s DC requirement, AC-coupling must be used. Figure 50 assumes that the LVPECL clock driver’s output impedance is 50Ω. R1 is used to DC-bias the LVPECL outputs prior to AC-coupling. Its value could be ranged from 140Ω to 240Ω depending on clock driver vendor’s requirement. R2 is used together with the SerDes reference clock receiver’s 50-Ω termination resistor to attenuate the LVPECL output’s differential peak level such that it meets the MPC8572E SerDes reference clock’s differential input amplitude requirement (between 200mV and 800mV differential peak). For example, if the LVPECL output’s differential peak is 900mV and the desired SerDes reference clock input amplitude is selected as 600mV, the attenuation factor is 0.67, which requires R2 = 25Ω.

Single-Ended Connection (Reference Only) 15.2.4 AC Requirements for SerDes Reference Clocks The clock driver selected should provide a high quality reference clock with low phase noise and cycle-to-cycle jitter. Phase noise less than 100KHz can be tracked by the PLL and data recovery loops and is less of a problem. Phase noise above 15MHz is filtered by the PLL. The most problematic phase noise MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 Freescale Semiconductor 79 High-Speed Serial Interfaces (HSSI) occurs in the 1-15MHz range. The source impedance of the clock driver should be 50 ohms to match the transmission line and reduce reflections which are a source of noise to the system. Table 59 describes some AC parameters common to SGMII, PCI Express and Serial RapidIO protocols. Table 59.

Measurment taken from single ended waveform. 2. Measurment taken from differential waveform. 3. Measured from -200 mV to +200 mV on the differential waveform (derived from SDn_REF_CLK minus SDn_REF_CLK). The signal must be monotonic through the measurement region for rise and fall time. The 400 mV measurement window is centered on the differential zero crossing. See Figure 52. 4. Matching applies to rising edge rate for SDn_REF_CLK and falling edge rate for SDn_REF_CLK. It is measured using a 200 mV window centered on the median cross point where SDn_REF_CLK rising meets SDn_REF_CLK falling. The median cross point is used to calculate the voltage thresholds the oscilloscope is to use for the edge rate calculations. The Rise Edge Rate of SDn_REF_CLK should be compared to the Fall Edge Rate of SDn_REF_CLK, the maximum allowed difference should not exceed 20% of the slowest edge rate. See Figure 53.

For better results, a source without significant unintended modulation should be used. SD2_REF_CLK/SD2_REF_CLK are not to be used with, and should not be clocked by, a spread spectrum clock source. 15.3 SerDes Transmitter and Receiver Reference Circuits Figure 54 shows the reference circuits for SerDes data lane’s transmitter and receiver. 50 Ω SD1_TXn or SD2_TXn SD1_RXn or SD2_RXn 50 Ω Transmitter Receiver 50 Ω SD1_TX n or SD2_TX n SD1_RX n or SD2_RX n 50 Ω Figure 54.

A TTX-EYE = 0.70 UI provides for a total sum of deterministic and random jitter budget of TTX-JITTER-MAX = 0.30 UI for the Transmitter collected over any 250 consecutive TX UIs. The TTX-EYE-MEDIAN-to-MAX-JITTER median is less than half of the total TX jitter budget collected over any 250 consecutive TX UIs. It should be noted that the median is not the same as the mean. The jitter median describes the point in time where the number of jitter points on either side is approximately equal as opposed to the averaged time value. 4. The Transmitter input impedance shall result in a differential return loss greater than or equal to 12 dB and a common mode return loss greater than or equal to 6 dB over a frequency range of 50 MHz to 1.25 GHz. This input impedance requirement applies to all valid input levels. The reference impedance for return loss measurements is 50 ohms to ground for both the D+ and D- line (that is, as measured by a Vector Network Analyzer with 50 ohm probes—see Figure 57). Note that the series capacitors CTX is optional for the return loss measurement. 5.

An external AC Coupling capacitor is required. 16.4.2 Transmitter Compliance Eye Diagrams The TX eye diagram in Figure 55 is specified using the passive compliance/test measurement load (see Figure 57) in place of any real PCI Express interconnect + RX component. There are two eye diagrams that must be met for the transmitter. Both eye diagrams must be aligned in time using the jitter median to locate the center of the eye diagram. The different eye diagrams differ in voltage depending whether it is a transition bit or a de-emphasized bit. The exact reduced voltage level of the de-emphasized bit is always relative to the transition bit. The eye diagram must be valid for any 250 consecutive UIs. A recovered TX UI is calculated over 3500 consecutive unit intervals of sample data. The eye diagram is created using all edges of the 250 consecutive UI in the center of the 3500 UI used for calculating the TX UI. NOTE It is recommended that the recovered TX UI is calculated using all edges in the 3500 consecutive UI interval with a fit algorithm using a minimization merit function (that is, least squares and median deviation fits).

Differential Receiver (RX) Input Specifications (continued) Symbol LRX-SKEW Parameter Total Skew Min Nominal Max Units Comments — — 20 ns Skew across all lanes on a Link. This includes variation in the length of SKP ordered set (for example, COM and one to five SKP Symbols) at the RX as well as any delay differences arising from the interconnect itself. Notes: 1. No test load is necessarily associated with this value. 2. Specified at the measurement point and measured over any 250 consecutive UIs. The test load in Figure 57 should be used as the RX device when taking measurements (also refer to the Receiver compliance eye diagram shown in Figure 56). If the clocks to the RX and TX are not derived from the same reference clock, the TX UI recovered from 3500 consecutive UI must be used as a reference for the eye diagram. 3. A TRX-EYE = 0.40 UI provides for a total sum of 0.60 UI deterministic and random jitter budget for the Transmitter and interconnect collected any 250 consecutive UIs. The TRX-EYE-MEDIAN-to-MAX-JITTER specification ensures a jitter distribution in which the median and the maximum deviation from the median is less than half of the total. UI jitter budget collected over any 250 consecutive TX UIs. It should be noted that the median is not the same as the mean. The jitter median describes the point in time where the number of jitter points on either side is approximately equal as opposed to the averaged time value. If the clocks to the RX and TX are not derived from the same reference clock, the TX UI recovered from 3500 consecutive UI must be used as the reference for the eye diagram. 4. The Receiver input impedance shall result in a differential return loss greater than or equal to 15 dB with the D+ line biased to 300 mV and the D- line biased to -300 mV and a common mode return loss greater than or equal to 6 dB (no bias required) over a frequency range of 50 MHz to 1.25 GHz. This input impedance requirement applies to all valid input levels. The reference impedance for return loss measurements for is 50 ohms to ground for both the D+ and D- line (that is, as measured by a Vector Network Analyzer with 50 ohm probes - see Figure 57). Note: that the series capacitors CTX is optional for the return loss measurement. 5. Impedance during all LTSSM states. When transitioning from a Fundamental Reset to Detect (the initial state of the LTSSM) there is a 5 ms transition time before Receiver termination values must be met on all un-configured Lanes of a Port. 6. The RX DC Common Mode Impedance that exists when no power is present or Fundamental Reset is asserted. This helps ensure that the Receiver Detect circuit does not falsely assume a Receiver is powered on when it is not. This term must be measured at 300 mV above the RX ground. 7. It is recommended that the recovered TX UI is calculated using all edges in the 3500 consecutive UI interval with a fit algorithm using a minimization merit function. Least squares and median deviation fits have worked well with experimental and simulated data. MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 88 Freescale Semiconductor PCI Express 16.5 Receiver Compliance Eye Diagrams The RX eye diagram in Figure 56 is specified using the passive compliance/test measurement load (see Figure 57) in place of any real PCI Express RX component. Note: In general, the minimum Receiver eye diagram measured with the compliance/test measurement load (see Figure 57) is larger than the minimum Receiver eye diagram measured over a range of systems at the input Receiver of any real PCI Express component. The degraded eye diagram at the input Receiver is due to traces internal to the package as well as silicon parasitic characteristics which cause the real PCI Express component to vary in impedance from the compliance/test measurement load. The input Receiver eye diagram is implementation specific and is not specified. RX component designer should provide additional margin to adequately compensate for the degraded minimum Receiver eye diagram (shown in Figure 56) expected at the input Receiver based on some adequate combination of system simulations and the Return Loss measured looking into the RX package and silicon. The RX eye diagram must be aligned in time using the jitter median to locate the center of the eye diagram. The eye diagram must be valid for any 250 consecutive UIs. A recovered TX UI is calculated over 3500 consecutive unit intervals of sample data. The eye diagram is created using all edges of the 250 consecutive UI in the center of the 3500 UI used for calculating the TX UI. NOTE The reference impedance for return loss measurements is 50. to ground for both the D+ and D- line (that is, as measured by a Vector Network Analyzer with 50. probes—see Figure 57). Note that the series capacitors, CTX, are optional for the return loss measurement. Figure 56. Minimum Receiver Eye Timing and Voltage Compliance Specification MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 Freescale Semiconductor 89 Serial RapidIO 16.5.1 Compliance Test and Measurement Load The AC timing and voltage parameters must be verified at the measurement point, as specified within 0.2 inches of the package pins, into a test/measurement load shown in Figure 57. NOTE The allowance of the measurement point to be within 0.2 inches of the package pins is meant to acknowledge that package/board routing may benefit from D+ and D– not being exactly matched in length at the package pin boundary. Figure 57. Compliance Test/Measurement Load 17 Serial RapidIO This section describes the DC and AC electrical specifications for the RapidIO interface of the MPC8572E for the LP-Serial physical layer. The electrical specifications cover both single and multiple-lane links. Two transmitters (short run and long run) and a single receiver are specified for each of three baud rates, 1.25, 2.50, and 3.125 GBaud. Two transmitter specifications allow for solutions ranging from simple board-to-board interconnect to driving two connectors across a backplane. A single receiver specification is given that accepts signals from both the short run and long run transmitter specifications. The short run transmitter should be used mainly for chip-to-chip connections on either the same printed circuit board or across a single connector. This covers the case where connections are made to a mezzanine (daughter) card. The minimum swings of the short run specification reduce the overall power used by the transceivers. The long run transmitter specifications use larger voltage swings that are capable of driving signals across backplanes. This allows a user to drive signals across two connectors and a backplane. The specifications allow a distance of at least 50 cm at all baud rates. All unit intervals are specified with a tolerance of +/– 100 ppm. The worst case frequency difference between any transmit and receive clock is 200 ppm. MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 90 Freescale Semiconductor Serial RapidIO To ensure interoperability between drivers and receivers of different vendors and technologies, AC coupling at the receiver input must be used. 17.1 DC Requirements for Serial RapidIO SD1_REF_CLK and SD1_REF_CLK For more information, see Section 15.2, “SerDes Reference Clocks.” 17.2 AC Requirements for Serial RapidIO SD1_REF_CLK and SD1_REF_CLK Figure 63lists the AC requirements.

Difference in the period of any two adjacent REFCLK cycles — — 80 ps — tREFPJ Phase jitter. Deviation in edge location with respect to mean edge location –40 — 40 ps — 17.3 8 ns applies only to serial RapidIO with 125-MHz reference clock Equalization With the use of high speed serial links, the interconnect media causes degradation of the signal at the receiver. Effects such as Inter-Symbol Interference (ISI) or data dependent jitter are produced. This loss can be large enough to degrade the eye opening at the receiver beyond what is allowed in the specification. To negate a portion of these effects, equalization can be used. The most common equalization techniques that can be used are as follows: • A passive high pass filter network placed at the receiver. This is often referred to as passive equalization. • The use of active circuits in the receiver. This is often referred to as adaptive equalization. 17.4 Explanatory Note on Transmitter and Receiver Specifications AC electrical specifications are given for transmitter and receiver. Long run and short run interfaces at three baud rates (a total of six cases) are described. The parameters for the AC electrical specifications are guided by the XAUI electrical interface specified in Clause 47 of IEEE 802.3ae-2002. XAUI has similar application goals to serial RapidIO, as described in Section 8.1. The goal of this standard is that electrical designs for serial RapidIO can reuse electrical designs for XAUI, suitably modified for applications at the baud intervals and reaches described herein. MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 Freescale Semiconductor 91 Serial RapidIO 17.5 Transmitter Specifications LP-Serial transmitter electrical and timing specifications are stated in the text and tables of this section. The differential return loss, S11, of the transmitter in each case shall be better than • –10 dB for (Baud Frequency)/10 < Freq(f) < 625 MHz, and • –10 dB + 10log(f/625 MHz) dB for 625 MHz ≤ Freq(f) ≤ Baud Frequency The reference impedance for the differential return loss measurements is 100 Ohm resistive. Differential return loss includes contributions from on-chip circuitry, chip packaging and any off-chip components related to the driver. The output impedance requirement applies to all valid output levels. It is recommended that the 20%-80% rise/fall time of the transmitter, as measured at the transmitter output, in each case have a minimum value 60 ps. It is recommended that the timing skew at the output of an LP-Serial transmitter between the two signals that comprise a differential pair not exceed 25 ps at 1.25 GB, 20 ps at 2.50 GB and 15 ps at 3.125 GB.

Additionally, the CJPAT test pattern defined in Annex 48A of IEEE 802.3ae-2002 is specified as the test pattern for use in eye pattern and jitter measurements. Annex 48B of IEEE 802.3ae-2002 is recommended as a reference for additional information on jitter test methods. 17.8.1 Eye Template Measurements For the purpose of eye template measurements, the effects of a single-pole high pass filter with a 3 dB point at (Baud Frequency)/1667 is applied to the jitter. The data pattern for template measurements is the Continuous Jitter Test Pattern (CJPAT) defined in Annex 48A of IEEE 802.3ae. All lanes of the LP-Serial link shall be active in both the transmit and receive directions, and opposite ends of the links shall use asynchronous clocks. Four lane implementations shall use CJPAT as defined in Annex 48A. Single lane implementations shall use the CJPAT sequence specified in Annex 48A for transmission on lane 0. The amount of data represented in the eye shall be adequate to ensure that the bit error ratio is less than 10-12. The eye pattern shall be measured with AC coupling and the compliance template centered at 0 Volts differential. The left and right edges of the template shall be aligned with the mean zero crossing points of the measured data eye. The load for this test shall be 100 Ω resistive +/– 5% differential to 2.5 GHz. 17.8.2 Jitter Test Measurements For the purpose of jitter measurement, the effects of a single-pole high pass filter with a 3 dB point at (Baud Frequency)/1667 is applied to the jitter. The data pattern for jitter measurements is the Continuous Jitter Test Pattern (CJPAT) pattern defined in Annex 48A of IEEE 802.3ae. All lanes of the LP-Serial link shall be active in both the transmit and receive directions, and opposite ends of the links shall use asynchronous clocks. Four lane implementations shall use CJPAT as defined in Annex 48A. Single lane implementations shall use the CJPAT sequence specified in Annex 48A for transmission on lane 0. Jitter shall be measured with AC coupling and at 0 Volts differential. Jitter measurement for the transmitter (or for calibration of a jitter tolerance setup) shall be performed with a test procedure resulting in a BER curve such as that described in Annex 48B of IEEE 802.3ae. 17.8.3 Transmit Jitter Transmit jitter is measured at the driver output when terminated into a load of 100 Ω resistive +/– 5% differential to 2.5 GHz. 17.8.4 Jitter Tolerance Jitter tolerance is measured at the receiver using a jitter tolerance test signal. This signal is obtained by first producing the sum of deterministic and random jitter defined in Section 8.6 and then adjusting the signal amplitude until the data eye contacts the 6 points of the minimum eye opening of the receive template shown in Figure 8-4 and Table 8-11. Note that for this to occur, the test signal must have vertical waveform symmetry about the average value and have horizontal symmetry (including jitter) about the mean zero crossing. Eye template measurement requirements are as defined above. Random jitter is calibrated using a high pass filter with a low frequency corner at 20 MHz and a 20 dB/decade roll-off below this. The required sinusoidal jitter specified in Section 8.6 is then added to the signal and the test load is replaced by the receiver being tested.

All multiplexed signals are listed only once and do not re-occur. For example, LCS5/DMA_REQ2 is listed only once in the local bus controller section, and is not mentioned in the DMA section even though the pin also functions as DMA_REQ2. 2. Recommend a weak pull-up resistor (2–10 KΩ) be placed on this pin to OVDD. 4. This pin is an open drain signal. 5. This pin is a reset configuration pin. It has a weak internal pull-up P-FET which is enabled only when the processor is in the reset state. This pull-up is designed such that it can be overpowered by an external 4.7-kO pull-down resistor. However, if the signal is intended to be high after reset, and if there is any device on the net which might pull down the value of the net at reset, then a pullup or active driver is needed. 6. Treat these pins as no connects (NC) unless using debug address functionality. 7. The value of LA[29:31] during reset sets the CCB clock to SYSCLK PLL ratio. These pins require 4.7-kΩ pull-up or pull-down resistors. See Section 19.2, “CCB/SYSCLK PLL Ratio.” 8. The value of LALE, LGPL2 and LBCTL at reset set the e500 core clock to CCB Clock PLL ratio. These pins require 4.7-kΩ pull-up or pull-down resistors. See the Section 19.3, “e500 Core PLL Ratio.” 9. Functionally, this pin is an output, but structurally it is an I/O because it either samples configuration input during reset or because it has other manufacturing test functions. This pin therefore be described as an I/O for boundary scan. 10. If this pin is configured for local bus controller usage, recommend a weak pull-up resistor (2-10 KΩ) be placed on this pin to BVDD, to ensure no random chip select assertion due to possible noise and so on. 11. This output is actively driven during reset rather than being three-stated during reset. 12. These JTAG pins have weak internal pull-up P-FETs that are always enabled. 13. These pins are connected to the VDD/GND planes internally and may be used by the core power supply to improve tracking and regulation. 14. Internal thermally sensitive diode. 15. If this pin is connected to a device that pulls down during reset, an external pull-up is required to drive this pin to a safe state during reset. 16. This pin is only an output in FIFO mode when used as Rx Flow Control. 17. Do not connect. 18. These are test signals for factory use only and must be pulled up (100 Ω - 1 KΩ) to OVDD for normal machine operation. 19. Independent supplies derived from board VDD. 20. Recommend a pull-up resistor (~1 KΩ) be placed on this pin to OVDD. 21. The following pins must NOT be pulled down during power-on reset: DMA1_DACK[0:1], EC5_MDC, HRESET_REQ, TRIG_OUT/READY_P0/QUIESCE, MSRCID[2:4], MDVAL, ASLEEP. 22. This pin requires an external 4.7-kΩ pull-down resistor to prevent PHY from seeing a valid Transmit Enable before it is actively driven. 23. This pin is only an output in eTSEC3 FIFO mode when used as Rx flow control. 24. TSEC2_TXD[1] is used as cfg_dram_type. IT MUST BE VALID AT POWER-UP, EVEN BEFORE HRESET ASSERTION.

When operating in DDR2 mode, connect Dn_MDIC[0] to ground through 18.2-Ω (full-strength mode) or 36.4-Ω (half-strength mode) precision 1% resistor, and connect Dn_MDIC[1] to GVDD through 18.2-Ω (full-strength mode) or 36.4-Ω (half-strength mode) precision 1% resistor. When operating in DDR3 mode, connect Dn_MDIC[0] to ground through 20-Ω (full-strength mode) or 40-Ω (half-strength mode) precision 1% resistor, and connect Dn_MDIC[1] to GVDD through 20-Ω (full-strength mode) or 40-Ω (half-strength mode) precision 1% resistor. These pins are used for automatic calibration of the DDR IOs. 26. These pins should be connected to XVDD_SRDS1. 27. These pins should be pulled to ground (XGND_SRDS1) through a 300-Ω (±10%) resistor. 28. These pins should be left floating. 29. These pins should be pulled up to TVDD through a 2–10 KΩ resistor. 30. These pins have other manufacturing or debug test functions. It is recommended to add both pull-up resistor pads to OVDD and pull-down resistor pads to GND on board to support future debug testing when needed. 31. DDRCLK input is only required when the MPC8572E DDR controller is running in asynchronous mode. When the DDR controller is configured to run in synchronous mode via POR setting cfg_ddr_pll[0:2]=111, the DDRCLK input is not required. It is recommended to tie it off to GND when DDR controller is running in synchronous mode. See the MPC8572E PowerQUICC™ III Integrated Host Processor Family Reference Manual Rev.0, Table 4-3 in section 4.2.2 “Clock Signals”, section 4.4.3.2 “DDR PLL Ratio” and Table 4-10 “DDR Complex Clock PLL Ratio” for more detailed description regarding DDR controller operation in asynchronous and synchronous modes. 32. EC_GTX_CLK125 is a 125-MHz input clock shared among all eTSEC ports in the following modes: GMII, TBI, RGMII and RTBI. If none of the eTSEC ports is operating in these modes, the EC_GTX_CLK125 input can be tied off to GND. 33. These pins should be pulled to ground (GND). 34. These pins are sampled at POR for General Purpose configuration use by software. Their value has no impact on the functionality of the hardware. MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 Freescale Semiconductor 117 Clocking 19 Clocking This section describes the PLL configuration of the MPC8572E. Note that the platform clock is identical to the core complex bus (CCB) clock. 19.1 Clock Ranges Table 76 provides the clocking specifications for both processor cores. Table 76.

Caution: The CCB to SYSCLK ratio and e500 core to CCB ratio settings must be chosen such that the resulting SYSCLK frequency, e500 (core) frequency, and CCB frequency do not exceed their respective maximum or minimum operating frequencies. Refer to Section 19.2, “CCB/SYSCLK PLL Ratio,” Section 19.3, “e500 Core PLL Ratio,” and Section 19.4, “DDR/DDRCLK PLL Ratio,” for ratio settings. 2. The processor core frequency speed bins listed also reflect the maximum platform (CCB) and DDR data rate frequency supported by production test. Running CCB and/or DDR data rate higher than the limit shown above, although logically possible via valid clock ratio setting in some condition, is not supported. The DDR memory controller can run in either synchronous or asynchronous mode. When running in synchronous mode, the memory bus is clocked relative to the platform clock frequency. When running in asynchronous mode, the memory bus is clocked with its own dedicated PLL with clock provided on DDRCLK input pin. Table 77 provides the clocking specifications for the memory bus. Table 77. Memory Bus Clocking Specifications Characteristic Memory bus clock frequency Min Max Unit Notes 200 400 MHz 1, 2, 3, 4 Notes: 1. Caution: The CCB clock to SYSCLK ratio and e500 core to CCB clock ratio settings must be chosen such that the resulting SYSCLK frequency, e500 (core) frequency, and CCB frequency do not exceed their respective maximum or minimum operating frequencies. Refer to Section 19.2, “CCB/SYSCLK PLL Ratio,” Section 19.3, “e500 Core PLL Ratio,” and Section 19.4, “DDR/DDRCLK PLL Ratio,” for ratio settings. 2. The Memory bus clock refers to the MPC8572E memory controllers’ Dn_MCK[0:5] and Dn_MCK[0:5] output clocks, running at half of the DDR data rate. 3. In synchronous mode, the memory bus clock speed is half the platform clock frequency. In other words, the DDR data rate is the same as the platform (CCB) frequency. If the desired DDR data rate is higher than the platform (CCB) frequency, asynchronous mode must be used. 4. In asynchronous mode, the memory bus clock speed is dictated by its own PLL. Refer to Section 19.4, “DDR/DDRCLK PLL Ratio.” The memory bus clock speed must be less than or equal to the CCB clock rate which in turn must be less than the DDR data rate. MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 118 Freescale Semiconductor Clocking As a general guideline when selecting the DDR data rate or platform (CCB) frequency, the following procedures can be used: • Start with the processor core frequency selection; • After the processor core frequency is determined, select the platform (CCB) frequency from the limited options listed in Table 79 and Table 80; • Check the CCB to SYSCLK ratio to verify a valid ratio can be choose from Table 78; • If the desired DDR data rate can be same as the CCB frequency, use the synchronous DDR mode; Otherwise, if a higher DDR data rate is desired, use asynchronous mode by selecting a valid DDR data rate to DDRCLK ratio from Table 81. Note that in asynchronous mode, the DDR data rate must be greater than the platform (CCB) frequency. In other words, running DDR data rate lower than the platform (CCB) frequency in asynchronous mode is not supported by MPC8572E. • Verify all clock ratios to ensure that there is no violation to any clock and/or ratio specification. 19.2 CCB/SYSCLK PLL Ratio The CCB clock is the clock that drives the e500 core complex bus (CCB), and is also called the platform clock. The frequency of the CCB is set using the following reset signals, as shown in Table 78: • SYSCLK input signal • Binary value on LA[29:31] at power up Note that there is no default for this PLL ratio; these signals must be pulled to the desired values. Also note that, in synchronous mode, the DDR data rate is the determining factor in selecting the CCB bus frequency, because the CCB frequency must equal the DDR data rate. In asynchronous mode, the memory bus clock frequency is decoupled from the CCB bus frequency. Table 78.

MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 Freescale Semiconductor 119 Clocking Table 79 describes the clock ratio between e500 Core0 and the e500 core complex bus (CCB). This ratio is determined by the binary value of LBCTL, LALE and LGPL2/LOE/LFRE at power up, as shown in Table 79.

Table 81 describes the clock ratio between the DDR memory controller complexes and the DDR PLL reference clock, DDRCLK, which is not the memory bus clock. The DDR memory controller complexes clock frequency is equal to the DDR data rate. When synchronous mode is selected, the memory buses are clocked at half the CCB clock rate. The default mode of operation is for the DDR data rate for both DDR controllers to be equal to the CCB clock rate in synchronous mode, or the resulting DDR PLL rate in asynchronous mode. In asynchronous mode, the DDR PLL rate to DDRCLK ratios listed in Table 81 reflects the DDR data rate to DDRCLK ratio, because the DDR PLL rate in asynchronous mode means the DDR data rate resulting from DDR PLL output. MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 120 Freescale Semiconductor Clocking Note that the DDR PLL reference clock input, DDRCLK, is only required in asynchronous mode. MPC8572E does not support running one DDR controller in synchronous mode and the other in asynchronous mode. Table 81.

These devices use the negative temperature coefficient of a diode operated at a constant current to determine the temperature of the microprocessor and its environment. It is recommended that each MPC8572E device be calibrated. The following are the specifications of the on-board temperature diode: Vf > 0.40 V Vf < 0.90 V Operating range 2–300 μA Diode leakage < 10 nA @ 125°C An approximate value of the ideality may be obtained by calibrating the device near the expected operating temperature. Ideality factor is defined as the deviation from the ideal diode equation: qVf ___ Ifw = Is e nKT – 1 Another useful equation is: KT q I IL H VH – VL = n __ ln __ Where: Ifw = Forward current Is = Saturation current Vd = Voltage at diode MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 Freescale Semiconductor 123 Thermal Vf = Voltage forward biased VH = Diode voltage while IH is flowing VL = Diode voltage while IL is flowing IH = Larger diode bias current IL = Smaller diode bias current q = Charge of electron (1.6 x 10 –19 C) n = Ideality factor (normally 1.0) K = Boltzman’s constant (1.38 x 10–23 Joules/K) T = Temperature (Kelvins) The ratio of IH to IL is usually selected to be 10:1. The above simplifies to the following: VH – VL = 1.986 × 10–4 × nT Solving for T, the equation becomes: nT = VH – VL __________ 1.986 × 10–4 MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 124 Freescale Semiconductor System Design Information 21 System Design Information This section provides electrical and thermal design recommendations for successful application of the MPC8572E. 21.1 System Clocking This device includes seven PLLs, as follows: 1. The platform PLL generates the platform clock from the externally supplied SYSCLK input. The frequency ratio between the platform and SYSCLK is selected using the platform PLL ratio configuration bits as described in Section 19.2, “CCB/SYSCLK PLL Ratio.” 2. There are two core PLLs whose ratios are individually configurable. Each e500 core PLL generates the core clock as a slave to the platform clock. The frequency ratio between the e500 core clock and the platform clock is selected using the e500 PLL ratio configuration bits as described in Section 19.3, “e500 Core PLL Ratio.” 3. The DDR Complex PLL generates the clocking for the DDR Controllers 4. The local bus PLL generates the clock for the local bus. 5. There is a PLL for the SerDes1 module to be used for PCI Express and Serial Rapid IO Interfaces. 6. There is a PLL for the SerDes2 module to be used for SGMII Interface. 21.2 21.2.1 Power Supply Design PLL Power Supply Filtering Each of the PLLs listed above is provided with power through independent power supply pins (AVDD_PLAT, AVDD_CORE0, AVDD_CORE1, AVDD_DDR, AVDD_LBIU, AVDD_SRDS1 and AVDD_SRDS2 respectively). The AVDD level should always be equivalent to VDD, and preferably these voltages are derived directly from VDD through a low frequency filter scheme such as the following. There are a number of ways to reliably provide power to the PLLs, but the recommended solution is to provide independent filter circuits per PLL power supply as illustrated in Figure 62, one to each of the AVDD pins. By providing independent filters to each PLL the opportunity to cause noise injection from one PLL to the other is reduced. This circuit is intended to filter noise in the PLLs resonant frequency range from a 500 kHz to 10 MHz range. It should be built with surface mount capacitors with minimum Effective Series Inductance (ESL). Consistent with the recommendations of Dr. Howard Johnson in High Speed Digital Design: A Handbook of Black Magic (Prentice Hall, 1993), multiple small capacitors of equal value are recommended over a single large value capacitor. Each circuit should be placed as close as possible to the specific AV DD pin being supplied to minimize noise coupled from nearby circuits. It should be possible to route directly from the capacitors to the AV DD pin, which is on the periphery of the 1023 FC-PBGA footprint, without the inductance of vias. MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 Freescale Semiconductor 125 System Design Information Figure 62 shows the PLL power supply filter circuits. 10 Ω VDD AVDD 2.2 µF 2.2 µF GND Low ESL Surface Mount Capacitors Figure 62. PLL Power Supply Filter Circuit NOTE It is recommended to have the minimum number of vias in the AVDD trace for board layout. For example, zero vias might be possible if the AVDD filter is placed on the component side. One via might be possible if it is placed on the opposite of the component side. Additionally, all traces for AVDD and the filter components should be low impedance, 10 to 15 mils wide and short. This includes traces going to GND and the supply rails they are filtering. The AVDD_SRDSn signal provides power for the analog portions of the SerDesn PLL. To ensure stability of the internal clock, the power supplied to the PLL is filtered using a circuit similar to the one shown in following figure. For maximum effectiveness, the filter circuit is placed as closely as possible to the AVDD_SRDSn ball to ensure it filters out as much noise as possible. The ground connection should be near the AVDD_SRDSn ball. The 0.003-µF capacitor is closest to the ball, followed by the two 2.2 µF capacitors, and finally the 1 Ω resistor to the board supply plane. The capacitors are connected from AVDD_SRDSn to the ground plane. Use ceramic chip capacitors with the highest possible self-resonant frequency. All traces should be kept short, wide and direct. SVDD_SRDSn 1.0 Ω AVDD_SRDSn 2.2 µF 1 2.2 µF 1 0.003 µF GND 1. An 0805 sized capacitor is recommended for system initial bring-up. Figure 63. SerDes PLL Power Supply Filter Note the following: • AVDD_SRDSn should be a filtered version of SVDD_SRDSn. • Signals on the SerDesn interface are fed from the XVDD_SRDSn power plane. 21.3 Decoupling Recommendations Due to large address and data buses, and high operating frequencies, the device can generate transient power surges and high frequency noise in its power supply, especially while driving large capacitive loads. This noise must be prevented from reaching other components in the MPC8572E system, and the device itself requires a clean, tightly regulated source of power. Therefore, it is recommended that the system designer place at least one decoupling capacitor at each VDD, TVDD, BVDD, OVDD, GVDD, and LVDD pin MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 126 Freescale Semiconductor System Design Information of the device. These decoupling capacitors should receive their power from separate VDD,TVDD, BVDD, OVDD, GVDD, and LVDD, and GND power planes in the PCB, utilizing short traces to minimize inductance. Capacitors may be placed directly under the device using a standard escape pattern. Others may surround the part. These capacitors should have a value of 0.01 or 0.1 µF. Only ceramic SMT (surface mount technology) capacitors should be used to minimize lead inductance, preferably 0402 or 0603 sizes. Additionally, it is recommended that there be several bulk storage capacitors distributed around the PCB, feeding the VDD, TVDD, BVDD, OVDD, GVDD, and LVDD planes, to enable quick recharging of the smaller chip capacitors. These bulk capacitors should have a low ESR (equivalent series resistance) rating to ensure the quick response time necessary. They should also be connected to the power and ground planes through two vias to minimize inductance. Suggested bulk capacitors—100–330 µF (AVX TPS tantalum or Sanyo OSCON). 21.4 SerDes Block Power Supply Decoupling Recommendations The SerDes1 and SerDes2 blocks require a clean, tightly regulated source of power (SVDD_SRDSn and XVDD_SRDSn) to ensure low jitter on transmit and reliable recovery of data in the receiver. An appropriate decoupling scheme is outlined below. Only surface mount technology (SMT) capacitors should be used to minimize inductance. Connections from all capacitors to power and ground should be done with multiple vias to further reduce inductance. • First, the board should have at least 10 x 10-nF SMT ceramic chip capacitors as close as possible to the supply balls of the device. Where the board has blind vias, these capacitors should be placed directly below the chip supply and ground connections. Where the board does not have blind vias, these capacitors should be placed in a ring around the device as close to the supply and ground connections as possible. • Second, there should be a 1-µF ceramic chip capacitor from each SerDes supply (SVDD_SRDSn and XVDD_SRDSn) to the board ground plane on each side of the device. This should be done for all SerDes supplies. • Third, between the device and any SerDes voltage regulator there should be a 10-µF, low equivalent series resistance (ESR) SMT tantalum chip capacitor and a 100-µF, low ESR SMT tantalum chip capacitor. This should be done for all SerDes supplies. 21.5 Connection Recommendations To ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal level. All unused active low inputs should be tied to VDD,TVDD, BVDD, OVDD, GVDD, and LVDD, as required. All unused active high inputs should be connected to GND. All NC (no-connect) signals must remain unconnected. Power and ground connections must be made to all external VDD,TVDD, BVDD, OVDD, GVDD, and LVDD, and GND pins of the device. 21.6 Pull-Up and Pull-Down Resistor Requirements The MPC8572E requires weak pull-up resistors (2–10 kΩ is recommended) on open drain type pins including I2C pins and MPIC interrupt pins. MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 Freescale Semiconductor 127 System Design Information Correct operation of the JTAG interface requires configuration of a group of system control pins as demonstrated in Figure 66. Care must be taken to ensure that these pins are maintained at a valid deasserted state under normal operating conditions as most have asynchronous behavior and spurious assertion gives unpredictable results. The following pins must NOT be pulled down during power-on reset: DMA_DACK[0:1], EC5_MDC, HRESET_REQ, TRIG_OUT/READY_P0/QUIESCE, MSRCID[2:4], MDVAL, and ASLEEP. The TEST_SEL pin must be set to a proper state during POR configuration. For more details, refer to the pinlist table of the individual device. 21.7 Output Buffer DC Impedance The MPC8572E drivers are characterized over process, voltage, and temperature. For all buses, the driver is a push-pull single-ended driver type (open drain for I2C). To measure Z0 for the single-ended drivers, an external resistor is connected from the chip pad to OVDD or GND. Then, the value of each resistor is varied until the pad voltage is OVDD/2 (see Figure 64). The output impedance is the average of two components, the resistances of the pull-up and pull-down devices. When data is held high, SW1 is closed (SW2 is open) and RP is trimmed until the voltage at the pad equals OVDD/2. RP then becomes the resistance of the pull-up devices. RP and RN are designed to be close to each other in value. Then, Z0 = (RP + RN)/2. OVDD RN SW2 Data Pad SW1 RP OGND Figure 64. Driver Impedance Measurement MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 128 Freescale Semiconductor System Design Information Table 84 summarizes the signal impedance targets. The driver impedances are targeted at minimum VDD, nominal OVDD, 105°C. Table 84.

See Table 1, Tj = 105°C. 21.8 Configuration Pin Muxing The MPC8572E provides the user with power-on configuration options which can be set through the use of external pull-up or pull-down resistors of 4.7 kΩ on certain output pins (see customer visible configuration pins). These pins are generally used as output only pins in normal operation. While HRESET is asserted however, these pins are treated as inputs. The value presented on these pins while HRESET is asserted, is latched when HRESET deasserts, at which time the input receiver is disabled and the I/O circuit takes on its normal function. Most of these sampled configuration pins are equipped with an on-chip gated resistor of approximately 20 kΩ. This value should permit the 4.7-kΩ resistor to pull the configuration pin to a valid logic low level. The pull-up resistor is enabled only during HRESET (and for platform /system clocks after HRESET deassertion to ensure capture of the reset value). When the input receiver is disabled the pull-up is also, thus allowing functional operation of the pin as an output with minimal signal quality or delay disruption. The default value for all configuration bits treated this way has been encoded such that a high voltage level puts the device into the default state and external resistors are needed only when non-default settings are required by the user. Careful board layout with stubless connections to these pull-down resistors coupled with the large value of the pull-down resistor should minimize the disruption of signal quality or speed for output pins thus configured. The platform PLL ratio, DDR complex PLL and e500 PLL ratio configuration pins are not equipped with these default pull-up devices. 21.9 JTAG Configuration Signals Correct operation of the JTAG interface requires configuration of a group of system control pins as demonstrated in Figure 66. Care must be taken to ensure that these pins are maintained at a valid deasserted state under normal operating conditions as most have asynchronous behavior and spurious assertion gives unpredictable results. Boundary-scan testing is enabled through the JTAG interface signals. The TRST signal is optional in the IEEE Std 1149.1 specification, but it is provided on all processors built on Power Architecture technology. The device requires TRST to be asserted during power-on reset flow to ensure that the JTAG boundary logic does not interfere with normal chip operation. While the TAP controller can be forced to the reset MPC8572E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 4 Freescale Semiconductor 129 System Design Information state using only the TCK and TMS signals, generally systems assert TRST during the power-on reset flow. Simply tying TRST to HRESET is not practical because the JTAG interface is also used for accessing the common on-chip processor (COP), which implements the debug interface to the chip. The COP function of these processors allow a remote computer system (typically, a PC with dedicated hardware and debugging software) to access and control the internal operations of the processor. The COP interface connects primarily through the JTAG port of the processor, with some additional status monitoring signals. The COP port requires the ability to independently assert HRESET or TRST to fully control the processor. If the target system has independent reset sources, such as voltage monitors, watchdog timers, power supply failures, or push-button switches, then the COP reset signals must be merged into these signals with logic. The arrangement shown in Figure 66 allows the COP port to independently assert HRESET or TRST, while ensuring that the target can drive HRESET as well. The COP interface has a standard header, shown in Figure 65, for connection to the target system, and is based on the 0.025" square-post, 0.100" centered header assembly (often called a Berg header). The connector typically has pin 14 removed as a connector key. The COP header adds many benefits such as breakpoints, watchpoints, register and memory examination/modification, and other standard debugger features. An inexpensive option can be to leave the COP header unpopulated until needed. There is no standardized way to number the COP header; so emulator vendors have issued many different pin numbering schemes. Some COP headers are numbered top-to-bottom then left-to-right, while others use left-to-right then top-to-bottom. Still others number the pins counter-clockwise from pin 1 (as with an IC). Regardless of the numbering scheme, the signal placement recommended in Figure 65 is common to all known emulators. 21.9.1 Termination of Unused Signals If the JTAG interface and COP header is not used, Freescale recommends the following connections: • TRST should be tied to HRESET through a 0 kΩ isolation resistor so that it is asserted when the system reset signal (HRESET) is asserted, ensuring that the JTAG scan chain is initialized during the power-on reset flow. Freescale recommends that the COP header be designed into the system as shown in Figure 66. If this is not possible, the isolation resistor allows future access to TRST in case a JTAG interface may need to be wired onto the system in future debug situations. • No pull-up/pull-down is required for TDI, TMS, TDO or TCK.

Populate this with a 10 Ω resistor for short-circuit/current-limiting protection. 3. The KEY location (pin 14) is not physically present on the COP header. 4. Although pin 12 is defined as a No-Connect, some debug tools may use pin 12 as an additional GND pin for improved signal integrity. 5.This switch is included as a precaution for BSDL testing. The switch should be closed to position A during BSDL testing to avoid accidentally asserting the TRST line. If BSDL testing is not being performed, this switch should be closed to position B. 6. Asserting SRESET causes a machine check interrupt to the e500 cores. Figure 66.
